This invention relates to cigar wrapping, and more particularly to a method for wrapping cigars and a cigar wrapping machanism, and lit is an object of the invention to provide improvements in cigar wrapping by accommodating to the different parts of the cigar the mode of applying the wrapper to the cigar bunch.

Another object of the invention is to provide a simple and inexpensive method and means for applying a wrapper to the bunch rapidly and nevertheless obtaining a very smooth cigar head end having an attractive appearance.

Further objects of the invention will appear from the following description when read in connection with the accompanying drawing showing an embodiment of the invention and wherein- Fig. 1 is a vertical side sectional View of a cigar wrapping mechanism embodying the invention;

Fig. 2 is an end view of the same mechanism, viewed in the direction II-II of Fig. l; and

Fig. 3.is a view similar to Fig. 2, showing the upper part of the mechanism in another operative position.

Referring to the drawing, a gang or cluster of bunch rollersy comprises three lower bunch rollers I which at their left ends are provided with pins 9, rotatably journalled in the frame 3. Furthermore, there are arranged two upper bunch rollers 2 which are at their left ends rotatably journalled in a bracket 4 which is pivotally mounted on a pin 5 in the frame 3. The right ends of the bunch rollers I and 2 are unsupported. A bunch A, inserted into the gang or cluster of bunch rollers, can project out of the mouth formed by the right ends of said rollers, and beyond said ends there is suflicient space to allow manual manipulating of the outwardly projecting bunch end B. The bunch may be inserted transversely or longitudinally between the bunch rollers. Y For that purpose, the rear end of the bracket 4 is pivotally connected to a rod 6 which is pivoted to a treadle 'I that is, in turn, pivotally journalled on a pin 8 in the frame 3. To the pins 9 of the bunch rollers are secured pinions I0 that mesh with a sun wheel II. The lowermost pinion I0 meshes with a gear wheel I2 that is `formed integrally with another gear wheel I3 and rotatably mounted on a shaft IB in the frame 3. The gear wheel I3 meshes with a gear wheel I5 which is secured to a stepwise rotating shaft I4 which is journalled in the frame 3 and driven in any well known manner.

In operation, the treadle 1 is depressed to elevate the bunch rollers 2. It may be suflicient to open the bunch rollers slightly, as shown in Fig. 3, since the bunch can be introduced longitudinally through the mouth formed by the free ends of the bunch rollers I and 2.` Thereby, the pinions of the bunch rollers 2 will mesh with the sun wheel II, even though' the bunch rollers are opened. When the bunch has been inserted so that its head end B projects out of the mouth of the bunch rollers I and 2 the latter are closed and rotated. A wrapper, having a flag end, for instance, is supplied manually to the bunch rollers as the latter rotate the body A of the bunch. At the end of said wrapping process the free wrapper end is applied manually to the free head end B of the bunch and smoothed out carefully on the bunch end. Suitably, this final step of wrapping is executed while the bunch still rotates. Then the treadle 'I is depressed to elevate the bunch rollers Z slightly and the bunch may be drawn longitudinally out of the bunch rollers by the hand that applied the wrapper-end to the bunch end.

What I claim is:

l. A method of wrapping cigars comprising slightly opening a cluster of bunch rollers, inserting a cigar bunch longitudinally into said cluster so that its head end projects beyond an end of said cluster, rotating the bunch within said cluster, manually applying a wrapper to the bunch, and gripping the projecting bunch head end and smoothing the wrapper end on said head end by hand.

2. In a cigar wrapping mechanism, a set of bunch rollers, a support for said rollers, means for spreading said rollers apart to admit a cigar bunch, an abutment for limiting the spreading movement of said rollers to allow introduction of the bunch longitudinally only into said Vset 0f bunch rollers, and driving means for rotating said rollers, said rollers being rotatably journalled f in said supportonly at one end and being connected to said' driving means at said ends, the other ends of said rollers forming an open mouth for the projecting head of a cigar bunch inserted `between said rollers, and said projecting head being accessible to allow manipulation thereof by gripping same by hand.
